Study Description

Brief Summary

An observational study aiming to assess the incidence and possible causes of post phacoemulsification watery eye.

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    This study will be conducted on patients who will undergo cataract extraction at Sohag university hospitals to evaluate the incidence of watery eyes in patients after phacoemulsification by one week , one month and three month.

    • Study Design: observational study.

    • Inclusion Criteria:

    Patients with age-related cataract.

    • Exclusion Criteria:
    1. patients with watering of eyes or ocular surface diseases or watering of the eyes .

    2. patients with previous ocular surgeries.

    3. patients with glaucoma, uveitis, corneal or retinal pathologies.

    • Preoperative Evaluation:
    Each patient will be subjected to the following:

    Detailed history taking and full ophthalmological examination. Fluorescein dye disappearance test. Syringing and probing. Schirmer's test. Tear break up time test. Measurement of punctal diameter by AS-OCT.

    • Operative procedures:
    1. regional anesthesia.

    2. phaco technique : stop and shop.

    3. cumulative dissipated energy (CDE ) &fluid flow.

    • Follow-up regimen: will be as follows:
    1. patients will be examined after surgery on: 1st postoperative week, 1st month, 3rd month.

    2. The following will be recorded for each patient:

    3. symptoms of watery eyes, visual acuity, IOP, slit lamp examination.

    4. dye disappearance test.

    5. Schirmer's test.

    6. tear break up time test.

    7. anterior segment OCT.

    Outcome Measures

    Primary Outcome Measures

    1. Assess the incidence and possible causes of post phacoemulsification watery eye. [Five months]

      Patients are examined preoperatively and postoperatively by flourescein disappearance test, probing and syringing, schirmer's test,tear breakup time test and anterior segment optical coherence tomography to detect incidence and causes of post phacoemulsification watery eye.
